Answer:
Natural Resources
Explanation:
High population density can be explained for many reasons, in this instance. There's a natural body of water for those to use and find food. Water usually attracts animals and also provides a source for hydration/other uses
The divergent plate boundaries are the places where the tectonic plates move away from each other. As they move part, which is actually driven by the convection currents in the mantle, they leave a gap between them of very thin and cracked crust. The convection currents manage to push the magma up with easy through this gap. As the magma pushes upward, it reaches the ocean floor, where the temperatures is significantly lower and it quickly cools off and forms new igneous rocks, or rather new crust. Since the magma is constantly rising and constantly making new crust, the new crust is pilling up, forming a mid ocean ridge with intense volcanic activity. Eventually, the rising magma will manage to come out on the surface and create volcanic islands, thus a chain of volcanic islands, which can even result in the formation of new large land of mass.
Answer:
Jobs focused on providing services are part of the tertiary economic sector.
Explanation:
There are four economic sectors based on the activities that are performed by the people. The primary economic sector, secondary economic sector, tertiary economic sector, and quaternary economic sector are the four economic sectors, all of which have their own unique characterisitcs. The tertiary economic sector is characterized by providing services.
ng serIn this economic sector, the jobs focus on providing services for the customers, and this is a sector that tends to be dominant in the countries that are well developed or the countries that have no other choices than to get engaged in it in order to have income. The well-developed countries are dominated by this sector because in the primary and secondary ones they don't need much labor force because of the advancements in technology, plus this sector is highly profitable. The countries that depend almost exclusively on tourism for income, like the big portion of the island nations at and around the tropics, have almost all of their labor force engaged in tourismm thus providing services for the tourist.
